Abstract
Provided are a silica glass yarn and a silica glass cloth which have a signal transmission speed that is made stable through stabilization of a characteristic impedance in addition to a low dielectric constant and a low loss. The silica glass yarn has a yarn habit density of 0.10 piece/cm or less of yarn habits each having a bending point with a radius of curvature of 5 mm or less and a bending angle of 120° or less. It is preferred that the silica glass yarn have a tensile strength of 2.0 GPa or more, and silica glass filaments forming the silica glass yarn each have a breaking start strength of 80.0% or more of the tensile strength of the silica glass yarn.
